Clarification of Intel's new M.2 CNVi WiFi/BT Standard.

From this document its clear that there is no way to make a standard M.2 WiFI BT card (either key type E or A+E) work in a CNVi M.2 slot even though it's a M.2 Key type E connector and will physical fit ... thats the bad news.


I have this problem with GA-H370N, neither of bcm94352 works.
But I'm wondering about
successes with these boards on GA-Z370N.
These cards are supposed to be the same in terms of wifi-bt.
Does it mean z370n has different CNVi connector that support wifi cards or it has different firmware?

Thanks

@verzunof,

CNVi is an Intel standard so there will be no difference between a CNVi slot on a H370N chipset motherboard to a Z370N chipset. Although physically similar to a M.2 type E slot the pin configuration of a CMVi M.2 slot is in-compatible with a standard M.2 type E keyed device. Only CNVi devices will work in a CNVi slot.

Best thing to do is to remove the CNVi card and install PCIe based solution if you have spare PCIe slot, if not then use a standard M.2 combo card in M.2 adapter as detailed in my post (as long as you have spare M.2 slot available).

Cheers
Jay

Z370N (Kaby Lake chipset) does not use Intel CNVi WiFi, bcm94352 replaces Intel Wifi and works.
H370N (Coffee Lake chipset) uses Intel CNVi WiFi, bcm94352 only works in another M.2 slot with an adapter. See KevinAgnes/Post #358.

Z370 is also Coffee Lake, however, according to this article, does not have CNVi
Author is wrong and did not do appropriate research
"Z390 motherboards released a year after Z370 and added the niceties introduced in the more mainstream options."
Z390/Coffee Lake chip set includes silicon CNVi "niceties," USB 3.1 Gen 2, etc.
Z370/Kaby Lake chip set does not include CNVi, however, supports Coffee Lake processors
An unplanned Intel consequence, all 200 Series motherboards support Coffee Lake processors (BIOS updated required)

Coffee Lake - Wikipedia/Chipsets:
The enthusiast Z370 (a rebranded Z270), launched alongside the first Coffee Lake CPUs in October 2017 ...

@toleda @jaymonkey it did work flawlessly!

(M.2-KEYM to M.2 KEYA+E adapter / M.2 KEYA+E to Mac WLAN / BCM94360CS2)

So for H370N-Wifi users and many others that don't have m2-WIFI or have m2-CNVi slots, this solution works.
It's kinda creepy with 2 adapters in a m2 key m slot!

but everything working!

I managed to use the antenna cables from the original intel cnvi wlan card!

Hi,

I have searched and searched on eBay for the red M.2 adapter in the pics. Just can't find it. Could you point me towards one? I would realy appreciate it :)

Thanks for your post!

Hello, I have PCI-E card with BCM94360CD (https://www.ebay.com/itm/Broadcom-BCM94360CD-802-11ac-1750Mbps-Desktop-PCi-E-WiFi-Adapter-Hackintosh-BT/132303186559?epid=1179343993&hash=item1ecde26a7f:g:eek:xUAAOSwNZtZ2aOg:rk:1:pf:0&LH_ItemCondition=1000&LH_BIN=1)

Both WiFi and BT are working, even iMessage, Continuity, Handoff, AirDrop, but I have noticed slow speeds on 5GHz network and a bit laggy mouse and keyboard when uploading over 20mbit/s. We have 500/50 mbit/s internet connection with AC wifi and my computer within 3m from router can reach max only 270/30 and average 160/30 mbit/s. For example, my Macbook pro at same position can reach 300/50 with no problems every time with max of 360 mbit/s download.

When I try 2.4GHz network, mouse and keyboard are unusable. Is this something that can be fixed by config edit or is it hardware issue?

Thank you.

Country Code: #a, why?
Suggestion from another user with similar problems. I'll try exact country code, could this be causing the issue?

I have looked up our wifi, it has not set the country code and it has no option to set it. Which country code should I use than?
